Diarrhea in baby goats, commonly called scours, is one of the most frequent health problems in young kids and can turn dangerous quickly due to dehydration. The cause depends largely on your kid’s age: newborns under two weeks are most vulnerable to bacterial and parasitic infections, while kids between five and eight weeks old are prime targets for coccidiosis. Dietary mistakes, particularly with milk replacer, are another common trigger at any age.
Age Matters: Narrowing Down the Cause
A baby goat’s age is the single most useful clue when figuring out what’s causing scours. In the first week or two of life, the most likely culprits are Cryptosporidium parvum (a microscopic parasite), certain strains of E. coli, and rotavirus. A Spanish study of neonatal goat kids with diarrhea found Cryptosporidium in 42% of sick kids and zero healthy ones, making it the most strongly associated pathogen in that age group. E. coli strains showed up in about 22% of cases, and rotavirus appeared in smaller outbreaks.
Between five and eight weeks of age, coccidiosis becomes the leading suspect. It’s the most common cause of diarrhea in indoor goat kids over four weeks old in many countries. Kids this age are exploring their environment, nibbling bedding and feed, and picking up coccidia oocysts from contaminated surfaces. The parasite multiplies inside the intestinal lining, and when kids swallow a large number of oocysts in a short period, clinical disease breaks out.
Clostridium perfringens, the bacterium behind enterotoxemia (sometimes called “overeating disease”), was found in about 11% of diarrheal goat kids in the same Spanish study and was absent in healthy animals. This one can kill very fast, so it’s worth knowing about even though it’s less common.
Coccidiosis: The Most Common Culprit
If your kid is roughly one to two months old and developing loose stools, coccidiosis should be at the top of your list. Mild cases start with feces that lose their normal pellet shape and become pasty, along with a dull coat, decreased appetite, and poor weight gain. More severe infections cause watery diarrhea that may contain blood, straining to defecate, lethargy, and noticeable weight loss. In the worst cases, kids go downhill rapidly with bloody diarrhea, abdominal pain, weakness, inability to stand, and death.
Diagnosis requires a fecal sample examined under a microscope to count oocysts. Your vet can prescribe targeted treatment. Sulfa-based medications are commonly used in the early stages of infection. Other antiparasitic drugs given as a single oral dose have shown good results and may need to be repeated. Prevention matters more than treatment here: keeping bedding dry, preventing fecal contamination of feed and water, and avoiding overcrowding all reduce the parasite load kids are exposed to.
Dietary Scours From Milk or Milk Replacer
Not all diarrhea comes from infection. Feeding mistakes are a frequent and entirely preventable cause. If you’re bottle-feeding with milk replacer, the most common errors are mixing the powder at the wrong concentration, feeding milk that’s too cold, feeding too much at once, or switching formulas suddenly. Milk replacer powder should be measured by weight on a kitchen scale, not scooped by volume. Even small inaccuracies in the ratio of powder to water can irritate a kid’s digestive tract.
Dietary scours typically look different from infectious diarrhea. The stool is often yellow or white and pasty rather than watery or bloody, and the kid usually stays bright and active. Correcting the feeding routine, making sure milk is consistently warm (around body temperature), and feeding smaller amounts more frequently will usually resolve the problem within a day or two. If it doesn’t improve, an infectious cause is more likely.
Enterotoxemia: The Fast Killer
Enterotoxemia caused by Clostridium perfringens type C or D deserves its own mention because it moves fast and is often fatal before you realize what’s happening. The bacterium lives in the gut at low levels but explodes in number when a kid suddenly gets more milk or grain than usual, such as after a missed feeding when it gorges, or when introduced to creep feed too quickly.
Symptoms can appear within 30 minutes of the bacterial overgrowth and include sudden refusal to eat, diarrhea, bloating, frothing at the mouth, difficulty breathing, shivering, staggering, and sometimes blindness. The toxins produced by the bacteria destroy the intestinal lining, causing rapid dehydration. This is a veterinary emergency. The good news is that enterotoxemia is highly preventable with a CD&T vaccine. Vaccinating does before kidding passes protective antibodies through colostrum, and kids can be vaccinated starting at around four weeks old.
Cryptosporidiosis and Zoonotic Risk
Cryptosporidium parvum deserves attention for two reasons: it’s extremely common in newborn kids, and it can infect you. This parasite spreads through the fecal-oral route, meaning you can pick it up by handling a sick kid and touching your mouth, or through contaminated water. In humans, Cryptosporidium causes watery diarrhea that can last one to two weeks. It’s particularly dangerous for young children, elderly people, and anyone with a weakened immune system.
In kids, cryptosporidiosis typically causes profuse watery diarrhea in the first two weeks of life. There’s no highly effective treatment available for goats, so management focuses on supportive care (fluids, warmth, nutrition) and preventing spread. Wear gloves when handling kids with diarrhea, wash your hands thoroughly afterward, and keep sick animals separated from the rest of the herd.
Checking for Dehydration
Dehydration is what actually kills most kids with scours, not the diarrhea itself. You can assess it at home with a simple skin pinch test: gently pull up a fold of skin on the kid’s neck and release it. In a well-hydrated animal, the skin snaps back flat immediately. If it stays tented or returns slowly, the kid is dehydrated and needs fluids.
Other signs of dehydration include dry or tacky gums, sunken eyes, cold ears and legs, and a weak suckle reflex. A normal rectal temperature for a goat is 101.3 to 103.5°F (38.5 to 39.7°C). A temperature below that range signals hypothermia, which often accompanies severe dehydration in young kids. A temperature above that range suggests active infection or inflammation.
Rehydration and Supportive Care
Getting fluids into a dehydrated kid is your most important immediate task. Commercial goat or livestock electrolyte solutions are ideal and available at most farm supply stores. In a pinch, you can make a basic oral rehydration solution by dissolving half a teaspoon of table salt and two tablespoons of sugar into four cups of warm water. This provides the sodium and glucose needed to help the intestines absorb water efficiently.
Offer electrolyte solution between milk feedings rather than replacing milk entirely, since kids still need calories and nutrition to fight off whatever is causing the problem. Use a bottle or syringe to get fluids in if the kid won’t drink on its own. Feed small amounts frequently, every two to four hours. If the kid is too weak to swallow, refuses to suckle, or has bloody stool, it needs veterinary intervention with intravenous or subcutaneous fluids.
Prevention Starts With Colostrum
Many cases of scours trace back to poor immune protection from inadequate colostrum intake. Goat kids need to consume roughly 10% of their body weight in colostrum during the first 12 to 14 hours of life. For a kid born at around 5.5 pounds, that’s approximately one cup total, divided into several small feedings. Colostrum delivers the antibodies a newborn needs to fight off the infections in its environment. Without it, kids are dramatically more susceptible to every pathogen on this list.
Beyond colostrum, the basics of prevention are cleanliness and management. Keep kidding pens clean and dry. Disinfect bottles and nipples between feedings. Avoid overcrowding. Introduce grain and browse gradually. Vaccinate does for CD&T before kidding so their colostrum carries protective antibodies. And isolate any kid showing signs of diarrhea immediately to protect the rest of the group.
